4-way, 3-position, pilot-to-shift directional valve
SERIES 1 / CAPACITY: 28 - 40 L/min. / CAVITY: T-61A
A-Spool
CONFIGURATION
X Control Standard Pilot
A Spool Configuration A to T Center
N Seal Material Buna-N
(none) Material/Coating Standard Material/Coating
Three-position, 4-way directional cartridges are spring-centered, 6-port directional valves that can be configured
from a choice of spool options. The supply port is port 3 and all ports will accept 5000 psi (350 bar). Capacity for
these pilot-to-shift valves is dependent on the spool type specified.

TECHNICAL FEATURES
All ports will accept 5000 psi (350 bar), including the x and y pilot ports (port 5 and port 6).
The reason for the different capacities, or performance limits, for the different spool configurations are flow forces. Flow forces are proportional to flow and pressure
drop. Typically, they resist the opening of a passage. Spool configurations that open passages as they spring center are the most susceptible. If the flow forces due
to the flow and pressure conditions exceed the centering spring force the valve may not shift completely. Higher flows may be used at lower pressures.
Leakage listed in technical data is for each path.
The pilot ports, 5 and 6, are positively sealed from the work ports.
Hardened spool and sleeve provide consistent and low spool leakage rates and excellent wear characteristics.
Incorporates the Sun floating style construction to minimize the possibility of internal parts binding due to excessive installation torque and/or cavity/cartridge
machining variations.
